querySelector() only giving one class instead of multiple

Question

In my code I am trying to get all classes which begin with priceList_ into an array for later use. the code I used to do that is: var prefix = document.querySelector('[class^="priceList_"]').className; There is one problem I am having with this code, which is that it only gives the first class with that prefix instead of giving an array of classes. Does anyone know the solution to this problem?

Answer 1

Use querySelectorAll(), it gives NodeList. It is iterable.
